Yii2 PHP Framework Remote Code Execution Vulnerability

漏洞信息

漏洞名称： Yii2 PHP Framework Remote Code Execution Vulnerability

漏洞编号：

• CVE： CVE-2024-58136

漏洞类型： 命令执行

漏洞等级： 严重

漏洞描述： Yii2是一个流行的PHP框架，广泛用于快速开发现代Web应用程序。它提供了丰富的功能，如MVC架构、表单验证、数据库抽象等，适用于各种规模的Web项目。此次漏洞影响的是Yii2框架的2.0.52之前版本。该漏洞的根源在于对JSON行为中的__class键值的不当验证，攻击者可以利用这一点实例化任意PHP类，从而实现远程代码执行（RCE）。这种漏洞的利用不需要任何形式的身份验证，攻击者可以直接通过网络发起攻击，对受影响的系统造成严重影响。由于Yii2框架的广泛应用，此漏洞的潜在影响范围非常广泛，可能导致服务器被完全控制，敏感数据泄露，甚至被用作进一步攻击的跳板。因此，所有使用受影响版本Yii2框架的开发者都应尽快升级到2.0.52或更高版本，以避免潜在的安全风险。
